5 killed in O.C. were related

Five people found dead over the weekend in an upscale San Clemente home were identified as a husband and wife, their twin daughters and the woman's mother -- none of whom had been seen in at least two weeks, a sheriff's official said Tuesday.

Although at least two of the family members suffered gunshot wounds, the investigation has not revealed how the family died.

Manas and Margrit Ucar were shot, but autopsies have not determined how they died, said Lt. Erin Giudice. Two handguns were found near their bodies, she said. One pistol was registered to Margrit Ucar. Giudice declined to comment about the other weapon.

There were no obvious signs of trauma to the bodies of the daughters and their grandmother, and toxicology tests are underway.

"The bodies were very decomposed. It will take a few weeks before we know the cause of death for any of them," Giudice said.

The couple's brothers went to the San Clemente house, after deputies twice had seen nothing amiss from outside, and discovered the bodies in a bottom-floor bedroom. Giudice said Margrit Ucar formerly owned a jewelry store, and the twins were students at UC San Diego.
